Title:
udev and lvm2 hang at boot
Status in linux package in Ubuntu:
Invalid
Status in udev package in Ubuntu:
Confirmed
Bug description:
I'm experiencing a really long wait when booting freshly installed
xubuntu 11.10 with only updates and mdadm + lvm2 installed. I have
managed to narrow it down somewhat but still looking for a fix.
After disabling splash and quiet from grub I noticed it's waiting at
/scripts/init-bottom/udev in initrd and continues after 61 seconds.
Not surprisingly i found a "udevadm control --timeout 61 --exit" line in
there. Well, why does it fail so badly it waits for timeout before exiting?
After quite a bit of googling I found this:

An init script (/scripts/init-bottom/udev in initrd) issues command
"udevadm control --timeouta --exit".
At the same time udevd is executing "/sbin/lvm vgchange -a y" (from
/lib/udev/rules.d/85-lvm2.rules) that calls ioctl to resume a logical
volume. After that lvm gets stuck forever. Booting continues after the
61 second timeout.

If you call vgchange or even vgscan from udev rule, it is completely wrong.
This is not lvm upstream udev rule btw.
This makes me slightly worried, does this cause any other problems
than a annoyingly slow boot? Is there any way to fix this? I this a
known issue?
